IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 119,949, dated October17, 1871.

To all whom it may concern:

Be it known that we, JOHN S. PERRY and ANDREW DIGKEY, ofthe city andcounty of AL bany in the State of New York, have invented an Improvementin Cook-Stoves; and we do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing making part .of this specication, in which- Figure1, Plate 1, is a section taken longitudinally and vertically through thecenter of the stove. Fig. 2, Plate 1, is a perspective view of Fig. 3,Plate 1, is a longitudinal section through the ash-pan and sifter. Fig.4, Plate 2, is a perspective view of the ash-pan and sifter. Fig. 5,Plate 2, is an enlarged longitudinal section through the center of theash-pan and sifter.

Similar letters of reference in dicate corresponding parts in theseveral iigures.

This invention relates to an improvement in cook-stoves, wherein thechamber beneath the grate and also the extended hearth of the stove areso constructed that all the ashes and cinders which fall through thegrate will be directed forward and outward into said extended hearth. Myobject is to combine with the hearths of stoves of the above-namedconstruction removable ash-pans, one of which is arranged within theother, the uppermost of which has a vibrating grated bottom, so thatashes can be conveniently sifted within the covered hearth and thecinders readily separated from them without permitting the escape ofdust into the room, after which the pans can be removed from the hearthand emptied of their contents, as will be hereinafter explained.

The following description of my invention will enable others skilled inthe art to understand it.

In the accompanying drawing', A represents the oven of the improvedstove, and B the lirechamber thereof. The flues a a are arranged above,below, and at the back of the oven A in any suitable manner, and theseflues communicate with a pipe, b, which forms part of the bottom andback side of a water-reservoir, R, and which communicates with the mainescape-Hue. In front of the lire-chamber B and arranged transverselyacross the stove in a vertical plane is a deiiector, D, which forms thefront of the hre-chamber and extends down to or below the level of thegrate. This deflector D may be iiat or corrugated. In front of thedeflector D is the front door C ofthe stove, which is hinged at h h andprovided with a fastening', Z, and which is composed of an outer walland an inner wall. The inner wall c of this door rises nearly to the topthereof', and forms with the outer wall an air -heating space, intowhich air is received through register openings c made through thisouter wall near the bottom of the door.

It will be seen from the above that, when the register c is open, airwill pass into the space between the two walls of the door O, thencerise to the top ofthe inner wall c, and descend through the spacebetween the walls c D beneath the grate, and iinally pass into thelirechamber through the grate in a highly-heated state. The air which isthus admitted into the fire-chamber is heated at a point above the levelof the hearth ofthe stove. Other means for heating the air admitted tothe lire-chamber may be adopted, although we prefer to employ the planabove set forth.

H is the hearth of the stove, on top of which is a closely-tting cover,G, which is hinged at p to the front wall of the stove so as to swinghorizontally. Vhen the cover G is in place, as shown in the drawing, itcloses a chamber or chest which communicates with the fire-chamber Bthrough an opening, 0, shown in Fig. 1, and which receives the ashes andcinders that fall from the rechamber upon an inclined plate or chute d.This chute directs the ashes and cinders downwardly and outwardly intothe hearth, as will be hereinafter explained. Within the depressedportion of the hearth H is a removable pan, J, which is provided with abail, t, and intended for receiving the ashes. This pan has arrangedwithin it another pan, t, the bottom s of which is a sieve, and slidesfreely upon lugs a' x. The sieve s receives a shakin g motion from ahooked handle that is inserted through an aperture, n. The sides of theinner pan iiare outwardly and prevent cinders from getting between it orthe edges of the sieve and the outer pan J.

It will be seen that theashes and cinders which fall from the re-chamberupon the inclined chute are conducted by the latter into the hollowhearth and delivered upon the sieve s, where the ashes can be separatedfrom the cinders and the latter returned into the firechamber. When theashes collect in large quantities in the pan J, this pan can be readilylifted from the hearth by its bail t and emptied. rlhe reservoir R issurmounted by a cast-metal frame, m, which is raised so that anythinglying upon the surface will have a tendency to fall outward or from thetop openings. The frame m has the pipe-collar formed on it, which, whenthe frame is bolted to the top of the stove and to the flangessurrounding the top edges of the body of the reservoir, will registerwith the vertical portion of the pipe b.

We are aware that cook-stoves have been made before our invention havingair-heating chests formed in their hearths, into which chests air wasadmitted through register-openings; but it will be seen that we do notsupply air to the re through the hearth-chest, but make this chest astight as possible from without, and supply the air for combustionthrough another chamber arranged above the hearth. y

Hence we obtain the following advantages, to wit: First, by hinging andlatching the cover G to the front of the stove we obtain atightly-litting cover, a result which cannot be obtained with any looseilat hearth-plate. Second, the cover is moved with ease, While under theold plan it is heavy and inconvenient to handle. Third, the cover beingmade tight and no opening left for the admission of air from Without,the chest becomes a reservoir for air, which is taken from it fromabove, which air is expanded in the chest by the heat to which it issubjected therein, and thus the chest becomes a kind of natural blowerfor aiding the draught of the stove.

Having described our invention, whatwe claim as new, and desire tosecure by Letters Patent, 1s

Combining with the hearth of a stove removable ash-pans, one of saidpans being seated within the other, and the uppermost pan having aremovable vibrating grated bottoni, substantially as and for thepurposes described.
